4 Removal and replacement procedures preliminary requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Flat-bladed screwdriver ● Magnetic screwdriver ● Phillips P0 and P1 screwdrivers Service considerations The following sections include some of the considerations that you must keep in mind during disassembly and assembly procedures.
Drive handling CAUTION: Drives are fragile components that must be handled with care. To prevent damage to the computer, damage to a drive, or loss of information, observe these precautions: Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system. Before handling a drive, be sure that you are discharged of static electricity.

Packaging and transporting guidelines Follow these grounding guidelines when packaging and transporting equipment: ● To avoid hand contact, transport products in static-safe tubes, bags, or boxes. ● Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging. ● Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations. ● Place items on a grounded surface before removing items from their containers.
Equipment guidelines Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation. ● When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips to connect a wrist strap.

10 Backup and recovery in Windows 8.1 To protect your information, use Windows backup and restore utilities to back up individual files and folders, back up your entire hard drive, create system repair media (select models only) by using the installed optical drive (select models only) or an optional external optical drive, or create system restore points. In case of system failure, you can use the backup files to restore the contents of your computer.
To recover your information using Automatic Repair, follow these steps: CAUTION: Some Automatic Repair options will completely erase and reformat the hard drive. All files you have created and any software installed on the computer are permanently removed. When reformatting is complete, the recovery process restores the operating system, as well as the drivers, software, and utilities from the backup used for recovery. 1. If possible, back up all personal files. 2.
website. Go to http://www.hp.com/support, select your country or region, and follow the on-screen instructions. CAUTION: Using a Windows 8.1 operating system media completely erases hard drive contents and reformats the hard drive. All files that you have created and any software that you have installed on the computer are permanently removed. When reformatting is complete, the recovery process helps you restore the operating system, as well as drivers, software, and utilities.
Using Windows Refresh or Windows Reset When your computer is not working properly and you need to regain system stability, the Windows Refresh option allows you to start fresh and keep what is important to you. The Windows Reset option allows you to perform detailed reformatting of your computer, or remove personal information before you give away or recycle your computer. The process described in this section provides a speedy, simple way to return the computer to its original state.
11 Backup and recovery in Windows 7 Your computer includes HP and Windows tools to help you safeguard your information and retrieve it if you ever need to. These tools will help you return your computer to a proper working state, all with simple steps. This section provides information about the following processes: ● Creating recovery media and backups ● Restoring and recovering your system Creating recovery media and backups Recovery after a system failure is only as good as your most recent backup.
well as select drivers and applications if the hard drive becomes corrupted. HP Recovery Disc Creator can create two kinds of recovery DVDs: ● Windows 7 operating system DVD—Installs the operating system without additional drivers or applications. ● Driver Recovery DVD—Installs specific drivers and applications only, in the same way that the HP Software Setup utility installs drivers and applications. Creating recovery media NOTE: The Windows 7 operating system DVD can be created only once.
To create a backup using Windows Backup and Restore: NOTE: The backup process may take over an hour, depending on file size and the speed of the computer. 1. Select Start > All Programs > Maintenance > Backup and Restore. 2. Follow the on-screen instructions to set up your backup, create a system image (select models only), or create system repair media (select models only).
CAUTION: Some Startup Repair options will completely erase and reformat the hard drive. All files you have created and any software installed on the computer are permanently removed. When reformatting is complete, the recovery process restores the operating system, as well as the drivers, software, and utilities from the backup used for recovery. 1. If possible, back up all personal files. 2. If possible, check for the presence of the Windows partition.
Using f11 recovery tools (select models only) CAUTION: Using f11 completely erases hard drive contents and reformats the hard drive. All files that you have created and any software that you have installed on the computer are permanently removed. The f11 recovery tool reinstalls the operating system and HP programs and drivers that were installed at the factory. Software not installed at the factory must be reinstalled. To recover the original hard drive image using f11: 1.
After the repair is completed: 1. Eject the Windows 7 operating system DVD and then insert the Driver Recovery DVD. 2. Install the Hardware Enabling Drivers first, and then install Recommended Applications.
12 Backing up, restoring, and recovering in Ubuntu Recovery after a system failure is as good as your most recent backup. As you add new software and data files, you should continue to back up your system on a regular basis to maintain a reasonably current backup. Creating a restore image The Recovery Media Creator allows you to repair or restore the computer to its original factory state. You can create restore image DVDs using DVD±RW optical drives. You can also create a restore image on a USB device.
Creating a restore image on a USB device NOTE: Be sure AC power is connected to the computer you begin this procedure. You can use Recovery Media Creator or the restore creation software to create a system restore image on a USB device. Verify the exact amount of free space on your storage device before you begin the creation process. For most models, you will need at least 4 GB of free space on the USB device.
Backing up your data files The Deja Dup Restore Tool allows you to back up your data files. You should back up your data files on a regular schedule to maintain a current backup. You can manually back up your information to an optional external drive, a network drive, or discs.
